[Evaluation of accuracy of body mass index in diagnosing of obesity in relation to body fat percentage in female aged 55-84 years].
Currently, body mass index (BMI) is frequently used for evaluation of obesity prevalence. This weight to height index does not reflect variability and changes in body composition components, and therefore, the BMI prevalence data may significantly differ from those based on the body fat percentage (%BFM). For the above reason, the primary aim of the study was to determine the prevalence of overweight and obesity according to %BFM and relate these data to BMI categories in women aged 55-84 years. ⋯ The results have shown that obesity may be diagnosed in women with lower BMI (i.e., < 30 kg/m2). For this reason we recommend to evaluate the prevalence of obesity primarily from BFM% in this age group.

The aim of the study was to clarify the change in underweight, overweight and obesity in seven year old Czech children since 1951. ⋯ These results suggest stabilisation of obesity and overweight prevalence in the Czech Republic in 7 years old children during the last 10 years. Underweight prevalence has remained low.
